CIRCULAR INDEPENDENT-NEEDLE KNITTING-MACHINE.

To all whom "it may ,concern:

Be it known that I, HEINRICH STOLL, Jr., a citizen of the German Empire,residing at Reutlingen, in the Kingdom of Wiirtemberg, Germany, haveinventedcertain new and-useful Improvements in CircularIndependent-Needle Knitting-Machines, of which the following is adescription, reference being had to the accompanying drawing, and to theletters and figures of reference marked thereon.

This invention relates to knitting machines of that general class inwhich double ended needles are employed on two superposed cylinders orother carriers and are transferred from cylinder to cylinder during theknitting operation.

One of the principal objects of the invention is to provide a machine inwhich a jacquard or similar pattern mechanism is employed to control themovements of the needles and thegeneral design or pattern of the work.

A further object of the invention is to so arrange the mechanism thatdifferent groups of needles are held in operation in successive order topermit the selective movement of the pattern mechanism.

A still further object of the invention is to provide for the divisionof the needles and the pattern devices into a corresponding number ofgroups each including a card cylinder or like member.

A still further object ofthe invention is to provide a machine by whichpatterned fabric, plain, purled and one and one (ribbed) fabric may beproduced.

The invention consists in the matters hereinafter described and referredto in the claims.

In the accompanying drawings :Figure 1 is a development of the twocylinders and cams, showing a portion of the pattern mechanism inelevation. Fig. 2 is a plan view'showing the sectional patternmechanism, the latter in this instance being divided into four parts.Fig. 3 is a vertical section of the machine. Fig. 4 is a development ofthe machine (partly contracted in width) showing the adjustment of theparts for the manufacture of smooth goods. Figs. 4 and f1 are sectionalviews of the cylinders on the corresponding marked section lines Fig. 4,the cams being omitted.

Fig. 5 is a view similar to Fig. 4, the machine being arranged for themanufacture of left and left goods. Figs. 5 =and 5 are sectional viewsof the cylinders on the correspondingly marked section lines Fig. 5, thecams being omitted. Fig. 6 is a view corresponding to Fig. 4, showingthe machine arranged for the manufacture of one and one goods. Figs. 6%and 6 are sectional views of the cylinders on the correspondingly markedsection lines of Fig. 6, the cams being omitted. Fig. 7 is aviewcorresponding to Fig. 4, showing the machine arranged to manufacturefigured goods. Figs. 7 a and 7 are sectional views of the cylinders onthe correspond- Specification of Letters Patent. Application filedOctober 14,1905. Serial No. 232,367.

' ingly marked section lines Fig. 7, the cams being omitted. Fig. 8 is asectional View of the cylinders on the The two cylinders a, a have theiraxes in the same vertical plane and are supported in superposed relationasgusual and at points near their adjacent ends are inclined flanges orcams y-y which serve in the usual manner to deflect the jacks outwardand free thence dles. The cylinders are stationary and around themrevolve the lower and upper cam rings 10, 1]. and above the upper camring is a jacquard or pattern mechanism J for controlling the characterof fabric produced.

The lower cam groove 1), v is continuous and the feet of the lower jacksb are in constant engagement therewith while the shape -or contour ofthe cam is such as to effect vertical movement of the jacks in movingthe needles 0.

Between the main operating portions 0, q and Ir of the lower cam thegroove 1) is horizontal and is so arranged that the jacks b and theneedles are retained inoperative in the lower cylinder and the length ofthis portion of the cam groove is equal to or greater than the width ofany one of the sections into which the jacquard or pattern mechanism isdivided, as will hereinafter appear.

The camsof, 'r, p, k and q of the upper cam ring 1] operate on the feetof the upper jacks b in the manipulation of theneedles c, the feet ofthe jacks traveling in the groove '10. Between the cam p and the camhowever, the top of the cam groove is open and when the top of the cam ppasses from under the feet of the upper jacks the latter are elevated tosuch an extent that they cannot be engaged by the cam is and again drawndown into the groove. The jacks when raised to this position are held upby small leaf springs g.carried by the upper cylinder.

The distance between the cams p and k is greater than the Width of oneof thesections into which the jacquard or pattern mechanism is dividedand this idle portion of the upper cam is above the idle portion 12 ofthe lower cam in order to permit the operation of such jacquardmechanism.

In the jack or needle grooves of the upper cylinder are arrangedauxiliary jacks d, the lower ends of which may be forced into engagementwith the upper ends of the main jacks b( in order to so depress thelatter that their feet may be caught by the cam is. The feet of theauxiliary jacks are under the control of an auxiliary cam t that issecured to and travels with the upper cam ring, this cam'i beingdisposed in a vertical plane in advance of the vertical plane of the camis so that fabric all of the upper jacks are depressed by the cams whenthe auxiliary jacks are forced down by the cam i the feet of the mainjacks b are depressed to such a position that they may be caught by thecam k.

The auxiliary jacks are under the direct control of the jacquardmechanism and this mechanism by raising the feet of the predeterminedjacks out of the path of the cam i, will control the character andpattern of goods produced. If the pattern mechanism raises an auxiliaryjack out of the path '0, the corresponding main jack is held up out ofneedle engaging position and the corresponding needle remains in thelower cylinder.

The jacquard mechanism is shown in the present instance as divided intofour equal sections, although there may be more or less sections asdictated by the size of the machine.

The sectional jacquard is stationary and is supported from the main postof the machine while the upper cam ring carries a revoluble cam 90 foractuating the jacquard. Each section includes a card cylinder ofordinary construction and a number of jack needles f corresponding toone fourth the number of auxiliary jacks d and these needles areconnected to the auxiliaryjacks d by cords h which pass through suitableguiding eyes. The card cylinders are moved in successive order againsttheir respective needles by means of the cam :0

Figs and 3 and those'needles f opposite the unperforated portions of thecards are thrust back toward the axes of the cylinders thereby raisingthe auxiliary jacks to which they are connected andinsuring theretention of the corresponding main jacks in elevated,

in-o wrativc position.

A ll of the auxiliary jacks elevated by the pattern mechanism aredepressed by a cam 2 once ineach revolution of the machine.

In the manufacture of plain fabrics the upper jacks assume thepositionshown in Fig. 4, all of said jacks remaining inoperative as inthis method of knitting the meshes are cast off only from the lowercylinder.

In the manufacture of purled or through and through i and k and all ofthe needles are transferred from cylinder to cylinder. I

In the manufacture of one and ofie (ribbed) goods as shown in Fig. 6,and patterned goods as shown in Fig. 7, the jacquard mechanism comesinto play and each section of the jacquard acts in turn on the group ofneedles under its control while such needles and their jacks are in theidle portions of the cams as previously described. Having thusparticularly described my invention, what I claim as new and desire tosecure by Letters Patent, isz- 1. The combination with a knittingmachine, of a jacquard mechanism formed of a number of independently operable sections, a revoluble; cam cylinder having needle- 5. in acircular knitting machine, stationary cylinders,
